Differential diagnosis

Scipopus (Scipopus) cartaboensis resembles Scipopus (Scipopus) nitidus sp. nov. in having a shiny epicephalon and shiny, bare patches on the orbital plate, but differs in the blue vitta on the scutum, the orange clypeus and epicephalon, and the short female T1+2 (~1.6× length of T3).

Description

LENGTH. 11–15 mm.

HEAD. Palpus orange, pale brown microtrichose and setulose on entire surface, narrow (length 4.5× height). Clypeus orange or light brown, width ~2.0× height, bare medially, white microtrichose in posterolateral corners. Frontal vitta dull, orange, microtrichose. Orbital plate orange with anterior, shiny, orange or light brown bare patches ( Fig. 11C ). Epicephalon orange or light brown, shiny, silvery microtrichose, narrow (width less than ⅔ of frontal vitta width at inner verticals), clearly delineated from upper frontal vitta. Paracephalon light brown or orange, slightly convex on outer portions. All head chaetotaxy well-developed.

THORAX. Scutum black-brown, black-brown microtrichose, with median blue sheen. Female cervical sclerite with slight anterior convex bump, otherwise relatively flat. Postpronotal lobe black-brown, pale microtrichose on ventral margin, setulose on outer margin. Notopleuron black-brown with pale microtrichosity outlining anterior notopleural seta and on ventral margin. Pleuron black-brown with the following microtrichosity: entirely white proepisternum and proepimeron, white on anteroventral ½ of anepisternum and posterodorsal corner, with ventral corner and remainder brown, almost entirely white on katepisternum, with median brown spot and dorsal patch ( Fig. 11F ), or white anteriorly and posteriorly ( Fig. 11G ), white on margins of katatergite. Legs black-brown; first fore and hind tarsomere dark brown with slight ventral golden fringe.

ABDOMEN (J+ ♀). Tergites black-brown. T1 with fine, long, white setae. Pleuron almost entirely dark brown or black, ventral ¼ of P2–6 pale grey ( Fig. 11G ).

FEMALE ABDOMEN. T1+2 ~1.6 × length of T3. Oviscape black-brown, white microtrichose on anterior ⅓, ~1.5–2.0 × length of T6. Combined spermathecal ducts short; common duct very short, almost absent. Paired spermathecal duct short (6.0–7.0 × length of paired spermathecae), narrow and curved basally, wider distally. Paired spermathecal stems same length as spermathecae, with rounded tubercles. Paired spermathecae narrower basally, wider apically, approximately teardrop-shaped. Single spermathecal duct arising from basal ¹/10 of paired duct, very narrow, less than ½ diameter and length of paired duct. Single spermatheca not clearly delineated, inornate, ending bluntly.

MALE ABDOMEN. T1+2 ~1.9× length of T3. Genital fork small, ~2.2× length of T6, with arms converging, nearly touching, inner basal process straight, ~½ length of arm. Epandrium of only available male broken, long setose posteroventrally. Basiphallus small, crescent-shaped. Basal distiphallus ~2.0 × length of phallic bulb. Phallic bulb short and small, length ≈ height, with upper chamber with posterior projection and lower chamber. Distal distiphallus broken off in only available male specimen, but apparently narrow. Phallapodeme not observed.

Remarks

A female of Scipopus (Scipopus) cartaboensis was photographed as it was ovipositing in rotting wood in Novo Airão, Brazil ( Fig. 12A ) and another individual was photographed in Presidente Figueriedo, Brazil, with an attached pseudoscorpion ( Fig. 12B ). The pseudoscorpion is not associated with the pinned specimen.

Distribution

Ecuador to Suriname ( Steyskal 1968), French Guiana (new record).
